Peter Koren, a Ducati enthusiast from the UK, found a 1978 Ducati 900GTS as a parts bike for his 750GT and 900SS. Looking a bit more at the old GTS, it wasn't as bad as he thought so instead of using the pieces he figured, "Why not fix it up?" It was past the restoration stage and he always liked the look of the Harley Davidson XR750 so maybe a flat tracker type conversion would look good. The result is the XR900 you see here and I think it's really sweet.
He reversed the fork to get the caliper behind the tubes to clean up the front. The tank is aluminum which he formed himself. He made the exhaust from old headers he had lying around. His Dad designed the graphics and his son helped paint and the whole bike looks like it came from the Ducati factory, which was exactly as Peter intended.
First the DesmoHarley and now this. I like it, ... a lot!
